Guess what an AK's 16.3" muzzle velocity is with a 123gr? 2290-2360fps
Even the 10.5" Grendel smokes the AK, both shooting the exact same bullet weight, same basic case size/length.
The AK goes subsonic around 500yds. The 10.5" Grendel is still supersonic at least to 800yds.
I know your looked upon very highly here...nearly God like...but your numbers are cooked to make your point. Import factory ammo disigned for guns built in the late 40's, up against modern factory guns and like ammo!
My 16" 7.62x39 AR's with hand loads equal my 6.5 velocities. I've been using CFE BLK powder and staying inside max loads. I have developed quite a new feeling for the hated AK round!
